Since this is another Jaars A/C maybe they will come up with a photo while with them in Peru as OB-T-714, pretty unlikely though, probably another CIA secret.

I was surprised that the -392 never entered production.  More power is better right? :)

If you think about it, a very similar model did enter production.

18 months later the H-395 with GO-480-G1D6 STCed with twin Rajay Turbochargers
came into production, similar to GSO-480-A1A6 engine.

Maybe someone smarter than me can argue which is better and why.

Added news clip.

Interesting that Cia. (company) Aerofoto Mexicana had engineering tests on the H-392 funded by the Company (American CIA).

I wonder if this name was misdirection by the CIA.

a photo found in my archives of N4207B before conversion to an H-392. Kind of a washed out color photo.
